Ive just recently learned the zen from the book blackbelt in blackjack and noticed that arnold talks about converting to the "true edge" by dividing RC/decks and then times 4 to the get a percentage, or can i just treat it like hi lo and just divide the RC/decks only to the get the true count. Also, what would be a good betting ramp for a 5k bankroll for the zen? Is Blackwood's ok to use?
